[PATCH v2 0/2] fix parsing of reboot= cmdline

From: Matteo Croce mcroce@microsoft.com

The parsing of the reboot= cmdline has two major errors: - a missing bound check can crash the system on reboot - parsing of the cpu number only works if specified last

Fix both, along with a small code refactor.

v1->v2: As Petr suggested, don't force base 10 in simple_strtoul(), so hex values are accepted as well.
